DNA topoisomerases release supercoils in DNA introduced during replication or transcription. How DNA topoisomerases impact transcription in the context of eukaryotic chromatin is poorly understood. In this study, using a floral stem cell model in Arabidopsis, we uncovered a role of TOP1a in Polycomb...

DNA topoisomerases release supercoils in DNA introduced during replication or transcription. How DNA topoisomerases impact transcription in the context of eukaryotic chromatin is poorly understood. In this study, using a floral stem cell model in Arabidopsis, we uncovered a role of TOP1M-NM-1 in Pol...

The main oncogenic driver in T-lymphoblastic leukemia (T-LL) is NOTCH1, which activates genes by forming chromatin-associated Notch transcription complexes. Gamma-secretase (GSI) inhibitor treatment prevents NOTCH1 nuclear localization, but most genes with NOTCH1 binding sites are insensitive to GSI...

Shotgun (bottom-up) approach has been widely applied in large-scale proteomics studies. The inherent shortages of shotgun approach lie in that the generated peptides often overwhelm the analytical capacity of current LC-MS/MS systems and that abundant proteins often hamper the identification of prot...
